3.27.2.2.5 Configuring alarm messages
If the counter starts a new count loop a alarm message is output (at the
same time as the event message) . Output
QO of function block CTR
supplies the signal. This signal is converted from the "boolean" format
into the "word" format (FB B_W), and is transferred to function block
S7AMA as the first event message word.
S7AMA is assigned a virtual data block No. for the user data area "alarm
messages" via a global operand (OP connection).
NOTE
The data block No. for the OP connection, assigned under
SIMADYN D, must also be assigned the configured area pointer for
alarm messages under ProTool/Lite.
